My presentinvention relates to sound producing and controlling devices, more particularly fortoyssuch as dolls. h

\nobjectoffthe invention is tou-provide a device of the above clifaracterrwhich shall be of low cost, both as vto material vand labor, which shaill be durable in 'constructioitn` and which shall. in operation simulate faithfully thecry of a baby; calling maina. l I

The invention is concerned with the-type of sound-.producing'mechanism in which the reed pipe has a lateralfopen'ing and in which the emission of air from the reed pipe is controlled by a slide valve action.

lIn order to produce moreparticularly the ma sound, itis jimportantthat the aperture in the reedpipe beopened quickly for forcefulvexpulsion of the air. To this end I provide the reed pipe, in the preferred embodiment, with a circular aperture and the valve rwith a control tongue slidable with re'-l spect to said aperture and of diameter smaller than that of said aperture, so that in the relative longitudinal shift of the reed pipe and the valve the aperture will be opened ata rate faster than the relative linear displacement of the parts. l

In the preferred' embodiment, the reed pipe is rigidly secured in the weightedhead ofthe bellows, so that it moves 'with said bellows in: the collapse of the latter, the controlling valve being` preferably stationary but mounted with'suicintfreedom to bev urged into' firm operativecoaction with said reed pipe by the expansion of a coil spring. The above and other features of my invention may be fullyv understood from the vaocompanying drawings, in which are shown some of the various possible embodiments of the invention.

Referring to the' drawings,v there isishown in the interior of the doll 11a, preferred form ofspui'id'producingland controlling device, comprising' .preferably- Aa cylindrical casing 2,l which inay'fbek of: card-board, .extending transversely.fromv .the frontwto the baclifof thedoll. The casingisf closed by:` a' cover cap 4 near the frontof ther doll with a piece of netting across thev op'enendthereof', the soundrescaping through an aperture 6 in the front of the doll. :Within thecasing 2f and-near the" lower end thereof is mounted a bellows",y thebottomof which 7 is secured as by glue within the lower end of the boXi2 tocon's'titutethe bottom thereof.,r The bellows inoliidesglthe usual circular' collapsible wall-18 andV h'a"s a weighted head 9, preferably -of'lead Ecv centrically-of the weightedhead is ai'reed pipe 10, which eXtendsat-right angles rto the head and is preferably securedl-inplace yby spending aperture inthe head The ordinary'y `reed e'lein'entris' secured within .the bellows endfof the,` reedV pipe, a fibre plug k12 being'preferably forced into thereed pipe andK having 'forced thereinto a ree-d element comprising a brassi'sei'nicylindrical element 113 taperingtoa point? at its,` en d as shown, andclosed laterally by a vibrating reed 14, no'p'a'rtof' tliejreed pipe extending beyo'ndthe-inirer surface of the forcing frictionally at its end into a correweightedh'ead, `The 'opposite endV of ther reed pipe is closed by means of a fibre plug 15. The reed pipe hasV preferably acircular aperture 16 in its sidethroug'lrwhichthe air forced from the bellows past the reed escapes'to produce the soun' l The control member for opening and' closl ing the ciroularaperture^ 16? vcomprisesI a valve plate member -17V withrespectl to'kwli'ieli` said reed pipe is slidablein operation, said valve plate being preferably mountedjin sub! stantia'lly fixed position with suflicient'freedom," however, tolV adapt fitself'readily for snugly contacting 'the reed pipe,` In`l the preferred embodiment, a tub'e 'or rod 18 servesto sustain the valve, sai'dtube extend# ing axially throiigh a sleeve or bushing` 19 in the weighted head 9 and throughtlie bel* lows and being secured as'at' 20 inthe lower end7' thereof.'- The valve plateill' yis pref efrably formed rigid with tliiuible 21;, Hair ing a reduced lug 22 jammed .into a corresponding aperture in the valve plate, the thimble being telescoped over a linger20 formed integral with rod 18 Aand extending at right angles to the length thereof. In the preferred embodiment a small'washer 23' encircles the finger' 2() and is interposed between the main length of the rod 18 and the thimble 21, a coil spring 24 encircling the thimble and exerting its pressure at one end against the washer 23 and at the other against the valve plate to urge it into firm coaction withV the reed pipe. It is preferred to form the plate as a curved segmentto tightly engage the cylindrical -reed pipe when pressed thereagainst by spring The valve preferably comprises an` integral stamped metal plate in form of a frame having side members 25, an upper cross piece 26and a lower cross piece 27,- defining a frame aperture 28. The cross p1ecef26 1s formed with `an integral downwardly entending tongue 29, in the preferred embodr ment, of a diameter somewhat smaller than 'i the diameter of the aperture 16 as best shown in Fig. 5, and asimilar tongue 30 eX- tends downward from the cross piece 27. Supporting thimble 26 for the valve, as shown, is preferably in the lower cross arm 27. The valve plate is preferably A,also formed with integral aligning tongues 31 formed as extensions of the side pieces 25 and extending toward each other for a substantial portion of the width of the plate, adding lengthand circumferential gripping area so as to prevent tilting or cooking of the relatively fiat plate in operation.

The doll is operated as any ordinary speaking or mama doll` of modern design. The doll being first laid prone or upon its face, it will be seen that the weighted head of the bellowswill drop to the position shown in Fig. 2, sucking in air through the usual checlrvalve `(not shown), the head sliding downward along rod 18 and the reed tube descending to position 'shown in which part of the aperture 16.extends beyond the extreme or outer edgecf the cross piece 26 of the valve. Then the doll is now replaced upon its back, the weighted head 9 descends toward the position shown in Fig. 1, drawing with it the reed tube as shown, the air from the bellows being forced past the reed through the reed tube for escape through the aperture 16, whenever the latter is open. It will be seen that the air will first escape through the exposed segment of aperture 16, which becomes closed, or choked, as it passes the cross piece 26 of the valve plate but in the continued descent of the reed tube the aperture 16 is quickly uncovered as the lower edge thereof passes the lower edge of tongue 27, the uncovering being at a rate materially quicker than that of the relative linear `displacement of the parts, by reason of the reduced width of the tongue relative to the aperture, so that the syllable ma is distinctly enunciated. After the aperture 16 is completely uncovered the vowel sound rod which may be cut from ordinary wire stock, the ordinary reed pipe, a valve which can be made by a simple stamping operation, and a thimble made by a simple screw machine operation. rPhe assembly is particularly expeditious in that it involves merely punch press operations to .combine the bushing 19 and the reed pipe 10 with the lead head, the assembly of the valve plate 1T and rod 18 being effected by a simple manipulation without tools, special fastening elements or adhesives of any hind.

In Fig. 6 is shown an alternative form of valve plate generally similar to that heretofore described but including a tonguev 31 formed integrally with one of the side pieces 25 of the plate and having an aperture 32 therein, into which the finger 20 of the rod 18 heretofore described vmay be fitted, the latter being directly encircled by a coil spring similar to that shown at 24.

It will thus be seen that there is herein described apparatus in which the several features of this invention are embodied, and which apparatus in its action attains the various objects of the invention and is well suited to meet the requirements of practical use.

As many changes could be made in the above construction, and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all inatter contained inthe above description or shown in the accompanying drawings shall be interpret-ed as illustrative and not in ,a limiting sense.
